It is the general object of the invention to provide a simple easily operated combination tool including in small compass all the equipmentnecessary, for woodworking, with means by which the devices for performing the differenttypes of work are available for alternative use, or may be moved to. retracted positions entirely out of the way of. the operator with a minimum loss of time in adjustment. V

More specifically, it is the object of the present invention to provide a novel and. improved means whereby a sander is made alternatively h available to perform the function of a jointer, the sanding disk being interchangeable with a lathe center; and generally thereby toi'mprove theefiectiveness, facility, and safety with which a machine of: this type may be adjusted and used; p l

V It1is a still further-object to provide an adjustable jointing-fence for use, with the sander disk, capable of-instant movement to andfrom aposition of work, and in which there is asuitable circular shouldered recess for the sanding disk, with; adjustable means for a .micrornetric axial movement to position the fence guiding faces about the sander disk thereby w regulate the depth of thecut in a given transfer of work; and an independent similarly oscillating sand ing table cooperatively usable with the'jointer fence." 1 i f ,Injth e drawing:" l V Figure 1 is 'aperspective view of the apparatus embodying the invention as viewed from the right front quarter; 7 f

Figure 2 is a fragmentary detail of the apparatus shown in Figure 1 illustrating different positions of adjustment to which certain parts maybe manipulated. 11 ,Figure 3 is a fragmentary detail in plan showing the headstock portion of the lathe andthe separated accessory equipment whichis normally mounted detachably thereon. i 1

Figure 4 is an enlarged detail view showing the headstock and sanding diskin front elevalustrating the jointer fence and table tion land V in longitudinal section. I

Likeparts are identified by the same reference charactersthroughoutthe several views.:

The apparatus is assembled upon a'lathe frame 9 having spaced'headstock bearings l0 and H from which the headstock spindle shaft IZprojects at both ends. Between the headstock mem-' bers I0 and II is a step pulley I 3 connected by belt II with the complementary step pulley l5 position onthe shaft l6 of the motor 11. The motor is carried on a pivotedplatform l8 which is slidably adjustable aswell aspivotally movable upona shortlength' of shafting' lfl carriediby, the frame. 7 r l the belt l4 under proper tension, and a long The weight'of the motor tends to .keep 1 I handle 20 projects forwardly-and upwardly to a position'within easyreach of" the operators hand, whereby the tension may be removed from the belt for shifting purposes and whereby also, the motor and its platform 18 may be bodily adjustable axially to register'difierent-elements of its four step pulley 'l5i with a given element of the three" step pulley l3. 1 i The tail stock 2|, and the tool rest. 22 are adjustable in the lathe bed in the usual way.' a

The head stock spindle l2 'may be provided with the usual driving and centering pointzshown at 24; but may alternatively be provided with a sanding disk 25; Rem'ovably applied, by :adhesive or otherwis'e;to the face of this disk; is a corresponding disk of sandpaper- 26 which servesnot merely forsanding infinishing operations, but also is used as ajointer through-means hereinafter to be described a a r Projecting 'rearwardly: from the headstock bracktsll'fl and II are. the arms 28 and 29 in which is fixed a rshaft .30 parallel to the bed of the lathe and spacedrearwardly therefrom, It is'particularly to be notedthat both ends ofthis shaft are exposed to. receive for support and adjustment numerous pieces of necessary accessory equipment. I .Among'these. pieces of accessory equipment is a saw table assmbly,'which is fully described in the above entitled parentapplication, detachably mountableu'p'on shaft '30-,at the-left end ofthe lathe frame 9. x V 1 Another device removably mounted-on the support 301is astable 3| which-isusedito carry'the work during the sanding operation; At times this tableis lowered acrossrthelathe bed in position for use as shown in Figures/l; 2 and 14. At such times its'forw'ard end is supported by legs 33 which rest on thelathebed. i At othertimes the table may be oscillated about support to an inoperative positionwholly clear of the lathe bed, in which it will not in any degree interfere with the use of'the lathe. i

When it isdesired to=use the sanding disk to perform a jointing function, a, specialjointing fence 351 is employed. This fence is also instantly adjustable between retracted and operative positions. 1 Figure 1 shows the fence in its operative and Figure 2 shows it elevated about support 3!! as a fulcrum in; its retractedposition. The fence 35 is recessed at 36 to receive the disk 25 and its forward and rear guiding surfaces ing the depth of cut made by the disk in a given transfer of work, (see Figure 3). Within limits, the exact depth of cut is subject to regulation, the jointer being provided with a rotatable pin 38 held in adjustment by set screw 39 and having an eccentric projection 40 which engages in an aperture 4| of the headstock bracket I I.

By rotating the pin 38 with a screw driver, the exact extent to which the abrasive-sheet projects from the forward face 42 of the fence may be regulated, whereby very accurately to control the exact effect of the sander upon the work.

As a piece of jointing apparatus the sander has proven to be exceptionally effective since it not only dresses thework but leaves it with a smooth finished surface. In addition, it is for safer for the workman than any previous known .j inter.

. .It is tobe'noted that the fence 35'and the sanding table 31, as well as the sanding disk 25 may bealmost instantly removed entirely from the apparatus, leaving the lathe completely unobstructed to receive any work within its capacity.

.I claim:
